The TPS7A3721DRVR from Texas Instruments is a high-accuracy, ultra-low-dropout linear voltage regulator designed for efficient power management. This device can supply up to 1A of output current with a fixed output voltage of 2.1V.
Key electrical specifications include a wide input voltage range from 2.2V to 5.5V and an impressive PSRR of 58dB to 37dB across a frequency range of 100Hz to 10kHz. The regulator features an ultra-low dropout voltage of typically 130mV at 1A, and a maximum of 200mV at 1A, ensuring minimal power loss. Its accuracy is rated at 1% overall over line, load, and temperature, with a nominal accuracy of 0.23%.
Protection features include over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO). The device also incorporates reverse current protection, a valuable feature for preventing damage in certain applications. It operates within an ambient temperature range of -40°C to 125°C.
The TPS7A3721DRVR is available in a compact 6-WSON (2x2 mm) package, suitable for surface mount applications. It requires a minimum load capacitance of 1µF for stable operation and exhibits excellent load transient response.
